Crohn's Disease Among the Poorest Billion: Burden of Crohn's Disease in Low- and Lower-Middle-Income Countries.

BACKGROUND: To establish the epidemiology and patterns of care of Crohn's Disease in low- and lower-middle-income countries. METHODS: A cross-sectional survey of gastroenterology providers in countries where the world's poorest billion live was conducted to learn more about the state of diagnostic and treatment capacity for Crohn's. Quantitative data were analyzed in R and Excel. RESULTS: A total of 46 survey responses from 15 countries were received, giving a response rate of 54.8%. All responses collected were from providers practicing in Africa and South Asia. The mean number of patients with Crohn's cared for in the last year was 89.5 overall but ranged from 0 reported at one facility in Rwanda to 1000 reported at two different facilities in India. Overall, Crohn's disease made up 20.6% of the inflammatory bowel disease diagnoses reported by survey respondents, with Africa exhibiting a larger proportion of Crohn's compared to ulcerative colitis than Asia. Most providers reported that patients with Crohn's have symptoms for 6-24 months prior to diagnosis and that 26-50% of their patients live in rural areas. The most reported diagnostic challenges are differentiating between Crohn's and intestinal tuberculosis, poor disease awareness, and lack of trained pathologists. The most widely reported challenge in managing Crohn's disease is patients' inability to afford biologics, reported by 65% of providers. CONCLUSION: Our study suggests there may be a greater burden of Crohn's disease in low- and lower-middle-income countries than is indicated in prior literature. Respondents reported many challenges in diagnosing and treating Crohn's disease.

Percutaneous Fluoroscopy-guided Retrieval of a Fractured Pelvic Drain after Caesarean Section: A Case Report.

Iatrogenic retention of surgical drains following drain entrapment and breakage is a never event and a preventable complication. The traditional approach for removing a fractured drain from the intra-peritoneal cavity involves exploratory laparotomy. However, over the last few decades, minimal access surgery has been a more popular retrieval method for retained surgical items from peritoneal and extraperitoneal cavities. We report a case of a 32-year-old woman with a fractured pelvic drain post-caesarean section. Postoperatively, the patient developed the signs of infection and features of bowel obstruction. The mechanical obstruction was ruled out by computed tomography scan. Multiple attempts were made to pull the pelvic drain out but the tube snapped, leaving about a quarter of its length. The drain remnant was retrieved using a non-invasive, inexpensive interventional radiology technique. We could not find any such report in the literature describing this innovative approach for retrieving a fractured pelvic drain. Keywords: case report; drain fragment retrieval; fractured pelvic drain; pelvic drain remnant.

An Atypical Case of Prolonged COVID-19 Infection.

Immunocompromised patients with COVID-19 can have prolonged disease courses that require escalation in care to inpatient or ICU settings. We report a case of a prolonged, active COVID-19 infection in an immunocompromised 61-year-old female with a history of non-Hodgkin's lymphoma. During her hospitalization, her cycle thresholds (CT) continued to worsen despite clinical improvement. We compared our patient's course and CTs to other reported cases in immunocompromised patients, investigating the efficacy of CTs and their use in evaluating disease progression and severity. RT-PCR tests targeting specific types of replicative viral RNA may have more utility in assessing disease severity and infectivity in immunocompromised patients. Our patient's disease course, similar to other reported cases, illustrates the need for improved treatment protocols and infection prevention for the immunocompromised population against SARS-CoV-2.

Diagnostic performance of volumetric laser endomicroscopy for Barrett's esophagus dysplasia amongst gastroenterology trainees.

BACKGROUND: Volumetric laser endomicroscopy (VLE) is an advanced imaging modality used in Barrett's esophagus (BE) surveillance. VLE image interpretation is challenged by subtle grayscale image variation across a large amount of data. Training in VLE interpretation is not standardized. This study aims to determine if VLE training can be incorporated into a gastroenterology (GI) fellowship curriculum with the use of a self-directed module. METHODS: A standardized, self-directed training module (30 min) was created explaining the background and established VLE criteria for the diagnosis of BE dysplasia. A VLE image dataset was generated from a multicenter VLE database of targeted biopsies. GI trainees were asked to grade each image for the presence or absence of the following criteria (I) increased surface optical frequency domain imaging (OFDI) signal intensity and (II) atypical glands and provide a final diagnosis (dysplastic vs. non-dysplastic). Diagnostic performance was calculated and results compared to VLE expert interpretation using histology as the gold-standard. RESULTS: The dataset included 50 VLE images (10 high-grade dysplasia, 40 non-dysplastic BE). VLE images were reviewed in a randomized and blinded fashion by 5 GI trainees with no prior VLE experience and 5 experienced VLE users. Sensitivity, specificity and accuracy of GI trainees was 83.3% (95% CI: 71.5-91.7%), 59.0% (95% CI: 51.6-66.0%), and 64.8% (95% CI: 58.5-70.7%) compared to 80.0% (95% CI: 67.7-89.2%), 79.5% (95% CI: 73.0-85.0%), and 79.6% (95% CI: 74.1-84.4%) for VLE experts respectively. The difference in specificity and accuracy between the two groups were statistically significant with P<0.001. CONCLUSIONS: A brief training session on VLE is inadequate to reach competency in interpretation of VLE by GI trainees. Additional experience is required to accurately interpret VLE images.

Safety and efficacy of sofosbuvir-velpatasvir-voxilaprevir for re-treatment of chronic hepatitis C virus infection in patients with previous direct-acting antiviral treatment failure in Rwanda (SHARED-3): a single-arm trial.

BACKGROUND: Hepatitis C virus (HCV) genotype 4 non-a/d subtypes, which frequently have NS5A resistance-associated substitutions, are highly prevalent in sub-Saharan Africa. These subtypes, particularly genotype 4r, have been associated with higher rates of failure of treatment regimens containing the NS5A inhibitors ledipasvir or daclatasvir, which are the most accessible direct-acting antivirals in low-income countries. Clinical evidence regarding the efficacy of re-treatment options for these subtypes is limited. We aimed to evaluate the safety and efficacy of sofosbuvir-velpatasvir-voxilaprevir for the treatment of adults in Rwanda with chronic HCV infection, predominantly of genotype 4, and a history of direct-acting antiviral treatment failure. METHODS: In this single-arm prospective trial, we enrolled adults (aged ≥18 years) with a HCV RNA titre of at least 1000 IU/mL, and a documented history of direct-acting antiviral failure. Patients were assessed for eligibility at a single study site after referral from hospitals with HCV treatment programmes throughout Rwanda, and participants for whom sofosbuvir-ledipasvir treatment had failed in the previous SHARED trial were also included. Participants with decompensated liver disease or hepatitis B virus co-infection were excluded. Participants were treated once daily with an oral fixed-dose combination tablet containing sofosbuvir (400 mg), velpatasvir (100 mg), and voxilaprevir (100 mg) for 12 weeks. The primary endpoint was the proportion of participants with a sustained virological response 12 weeks after completion of treatment (SVR12) in the intention-to-treat population. Viral sequencing of NS3, NS5A, and NS5B genes was done at baseline in all participants and at end of follow-up (week 24) in participants with treatment failure. The study is registered with ClinicalTrials.gov (NCT03888729) and is completed. FINDINGS: Between Sept 23, 2019, and Jan 10, 2020, 49 individuals were screened and 40 participants were enrolled. 20 (50%) were female, 20 (50%) were male, median age was 63 years (IQR 56-68), and median HCV viral load was 6·2 log10 IU/mL (5·8-6·5) at baseline. The genotype subtypes identified were 4r (18 [45%] participants), 4k (six [15%]), 4b (five [13%]), 4q (four [10%]), 4l (two [5%]), 4a (one [3%]), 4m (one [3%]), and 3h (one [3%]). One (3%) genotype 4 isolate could not be subtyped, and one (3%) isolate was of unknown genotype. All successfully sequenced isolates (33 [83%]) had at least two NS5A resistance-associated substitutions and 25 (63%) had three or more. 39 (98% [95% CI 87-100]) participants had SVR12. Seven (18%) participants had a total of ten grade 3, 4, or 5 adverse events, including three (8%) cases of hypertension, and one (3%) case each of cataract, diabetes, gastrointestinal bleeding, joint pain, low back pain, vaginal cancer, and sudden death. Four of these events were categorised as serious adverse events resulting in hospitalisation. The one sudden death occurred at home from an unknown cause 4 weeks after the completion of treatment. No serious adverse event was determined to be related to the study drug or resulted in treatment discontinuation. INTERPRETATION: A 12 week course of sofosbuvir-velpatasvir-voxilaprevir is safe and efficacious for the re-treatment of individuals infected with HCV genotype 4 non-a/d subtypes with frequent baseline NS5A resistance-associated substitutions, following failure of previous direct-acting antiviral treatment. Improved affordability and access to sofosbuvir-velpatasvir-voxilaprevir in regions with these subtypes is crucial. FUNDING: Gilead Sciences.

Safety and efficacy of sofosbuvir-velpatasvir to treat chronic hepatitis C virus infection in treatment-naive patients in Rwanda (SHARED-3): a single-arm trial.

BACKGROUND: Hepatitis C virus (HCV) genotype 4 is the predominant type of HCV found in sub-Saharan Africa. Various genotype 4 subtypes, such as 4r, frequently have resistance-associated substitutions that can increase rates of treatment failure with common direct-acting antiviral regimens. In-vitro studies suggest that the NS5A inhibitor velpatasvir is effective against viral isolates containing such resistance-associated substitutions, but its clinical efficacy against genotype 4 non-a/d subtypes in sub-Saharan Africa remains to be confirmed. We aimed to evaluate the safety and efficacy of sofosbuvir-velpatasvir among adults chronically infected with HCV and naive to direct-acting antiviral treatment in Rwanda, where genotype 4 non-a/d subtypes predominate. METHODS: In this single-arm prospective trial, we enrolled adults (age ≥18 years) in Rwanda who had chronic HCV infection and a plasma HCV RNA titre of at least 1000 IU/mL. Patients were referred from hospitals with HCV treatment programmes throughout Rwanda and were sequentially enrolled and assessed for eligibility at a single study site. Individuals with decompensated liver disease or hepatitis B virus co-infection were excluded. Participants were given an oral fixed-dose combination tablet of sofosbuvir (400 mg) and velpatasvir (100 mg) once-daily for 12 weeks. The primary endpoint was the proportion of participants with a sustained virological response 12 weeks after completion of treatment (SVR12) in the intention-to-treat population. Viral sequencing of the NS5A and NS5B genes was done at baseline for all participants and end of follow-up (week 24) for participants who did not have SVR12. This study is registered with ClinicalTrials.gov (NCT03888729) and is completed. FINDINGS: Between Sept 23, 2019, and Jan 10, 2020, 73 individuals were screened for eligibility, of whom 12 (16%) were excluded and 61 (84%) were enrolled. 40 (66%) participants were female, 21 (34%) were male, median age was 64 years (IQR 51-74), and median baseline HCV viral load was 5·7 log10 IU/mL (5·2-6·2). The genotypes identified among the participants were 4k (28 [46%] participants), 4r (11 [18%]), 4v (eight [13%]), 4q (five [8%]), 4l (three [5%]), 4b (one [2%]), 4c (one [2%]), and one undetermined genotype 4 subtype. Three isolates could not be sequenced and were of indeterminate genotype. Of the 55 HCV isolates that were successfully sequenced, all had at least two NS5A resistance-associated substitutions. 59 (97% [95% CI 89-99]) participants had SVR12. 18 (30%) participants had grade 3 adverse events (including 12 [20%] with hypertension), and none had grade 4 adverse events. Four (7%) participants had serious adverse events, including one asthma exacerbation, one abscess, one uterine myoma, and one pelvic fracture related to a motor vehicle accident. No serious adverse events were attributed to the study drug and no adverse event resulted in discontinuation of the study drug. INTERPRETATION: A 12-week regimen of sofosbuvir-velpatasvir is safe and efficacious in treating chronic HCV genotype 4 infection in patients in Rwanda. This regimen could be an effective treatment option in regions known to have a high prevalence of HCV genotype 4 of diverse non-a/d subtypes. FUNDING: Gilead Sciences.

Addressing the Impact of Noncommunicable Diseases and Injuries (NCDIs) in Ethiopia: Findings and Recommendations from the Ethiopia NCDI Commission.

BACKGROUND: Noncommunicable diseases and injuries (NCDIs) are the leading causes of premature mortality globally. Ethiopia is experiencing a rapid increase in NCDI burden. The Ethiopia NCDI Commission aimed to determine the burden of NCDIs, prioritize health sector interventions for NCDIs and estimate the cost and available fiscal-space for NCDI interventions. METHODS: We retrieved data on NCDI disease burden and concomitant risk factors from the Global Burden of Disease (GBD) Study, complemented by systematic review of published literature from Ethiopia. Cost-effective interventions were identified through a structured priority-setting process and costed using the One Health tool. We conducted fiscal-space analysis to identify an affordable package of NCDI services in Ethiopia. RESULTS: We find that there is a large and diverse NCDI disease burden and their risk factors such as hypertension and diabetes (these conditions are NCDIs themselves and could be risk factors to other NCDIs), including less common but more severe NCDIs such as rheumatic heart disease and cancers in women. Mental, neurological, chronic respiratory and surgical conditions also contribute to a substantial proportion of NCDI disease burden in Ethiopia. Among an initial list of 235 interventions, the commission recommended 90 top-priority NCDI interventions (including essential surgery) for implementation. The additional annual cost for scaling up of these interventions was estimated at US$550m (about US$4.7 per capita). CONCLUSIONS: A targeted investment in cost-effective interventions could result in substantial reduction in premature mortality and may be within the projected fiscal space of Ethiopia. Innovative financing mechanisms, multi-sectoral governance, regional implementation, and an integrated service delivery approach mainly using primary health care are required to achieve these goals.

No difference in PROMs between robotic-assisted CR versus PS total knee arthroplasty: a preliminary study.

The purpose of this study was to determine if significant clinical differences exist in patient-reported outcome measures (PROMs) between PS and CR TKAs implanted using robotic-assisted technology. This was an IRB-approved retrospective study from an institutional database evaluating 214 knees in 190 patients. Inclusion criteria included: primary RA-TKA, age 22-89 at the time of surgery, preoperative coronal limb deformity within 15º of neutral alignment, and minimum 1-year follow-up. The PS cohort consisted of 103 patients with 107 RA-TKAs, whereas the CR cohort consisted of 87 patients with 107 RA-TKAs. Cohorts were compared on the basis of demographics and PROMs (KSS knee, KSS function, FJS-12, KOOS-JR, WOMAC, and 5-point satisfaction Likert scale) collected preoperatively and at 1-year follow-up. Statistical analyses comparing measures were conducted via Student's t tests for continuous data and Chi-squared analyses for categorical data. There were no significant differences identified in short-term PROMs at 1-year follow-up between cohorts (all p values > 0.05). 93.1% of patients with CR knees and 94.7% of patients with PS knees reported a satisfaction level of "very satisfied" or "satisfied". Revision arthroplasty occurred in six knees (2.8%, 3 knees in CR cohort, 3 knees in PS cohort) with no differences in overall complications between groups. The use of RA-TKA technology promoted high patient satisfaction scores within this study, independent of CR or PS implant type with no significant differences in PROMs, satisfaction, revisions, or complications between the two groups.

Prioritizing Health-Sector Interventions for Noncommunicable Diseases and Injuries in Low- and Lower-Middle Income Countries: National NCDI Poverty Commissions.

Health sector priorities and interventions to prevent and manage noncommunicable diseases and injuries (NCDIs) in low- and lower-middle-income countries (LLMICs) have primarily adopted elements of the World Health Organization Global Action Plan for NCDs 2013-2020. However, there have been limited efforts in LLMICs to prioritize among conditions and health-sector interventions for NCDIs based on local epidemiology and contextually relevant risk factors or that incorporate the equitable distribution of health outcomes. The Lancet Commission on Reframing Noncommunicable Diseases and Injuries for the Poorest Billion supported national NCDI Poverty Commissions to define local NCDI epidemiology, determine an expanded set of priority NCDI conditions, and recommend cost-effective, equitable health-sector interventions. Fifteen national commissions and 1 state-level commission were established from 2016-2019. Six commissions completed the prioritization exercise and selected an average of 25 NCDI conditions; 15 conditions were selected by all commissions, including asthma, breast cancer, cervical cancer, diabetes mellitus type 1 and 2, epilepsy, hypertensive heart disease, intracerebral hemorrhage, ischemic heart disease, ischemic stroke, major depressive disorder, motor vehicle road injuries, rheumatic heart disease, sickle cell disorders, and subarachnoid hemorrhage. The commissions prioritized an average of 35 health-sector interventions based on cost-effectiveness, financial risk protection, and equity-enhancing rankings. The prioritized interventions were estimated to cost an additional US$4.70-US$13.70 per capita or approximately 9.7%-35.6% of current total health expenditure (0.6%-4.0% of current gross domestic product). Semistructured surveys and qualitative interviews of commission representatives demonstrated positive outcomes in several thematic areas, including understanding NCDIs of poverty, informing national planning and implementation of NCDI health-sector interventions, and improving governance and coordination for NCDIs. Overall, national NCDI Poverty Commissions provided a platform for evidence-based, locally driven determination of priorities within NCDIs.

Risk factors for difficult-to-treat hepatitis C virus genotype 4r in Rwanda and implications for elimination in sub-Saharan Africa.

In sub-Saharan Africa, there exist distinct HCV genotype (GT) subtypes harbouring resistance-associated substitutions to commonly used non-structural protein 5A (NS5A) inhibitor-based direct-acting antiviral (DAA) regimens. In particular, GT4r subtype has demonstrated high rates of treatment failure. In the absence of routine viral sequencing in sub-Saharan Africa, it is important to identify sociodemographic, epidemiologic, and clinical characteristics that may be associated with GT4r infection. Methods: A secondary analysis was performed on data from 300 adults with HCV GT4 enrolled in a prospective trial assessing the safety and efficacy of sofosbuvir-ledipasvir in Rwanda in 2017. The association between characteristics at enrolment and GT subtype was assessed by chi-square analysis and logistic regression. In multivariate analysis, there were a higher proportion of participants with GT4r subtype with age <40 years (OR: 3.6, 95% CI: 1.3-10.5, p = 0.02), previous hospitalization (OR: 2.5, 95% CI: 1.3-5.0, p = 0.006), previous surgery (OR: 2.2, 95% CI: 1.1-4.2, p = 0.03), cirrhosis (OR: 3.2, 95% CI: 1.3-7.5, p = 0.008) and baseline HCV RNA >1 million IU/ml (OR: 3.4, 95% CI: 1.6-6.9, p = 0.001). Rwandan adults with GT4r are more likely to be younger, have a history of hospital admissions and surgeries and have more active or advanced liver disease compared to those with other GT4 subtypes. In the absence of advanced diagnostics to assess GT subtype, patients with these characteristics may warrant closer monitoring for treatment failure or alternative DAA regimens. More treatment experience with diverse DAA regimens is urgently needed for GT subtypes particular to this region.

A Preparedness Model for Mother-Baby Linked Longitudinal Surveillance for Emerging Threats.

INTRODUCTION: Public health responses often lack the infrastructure to capture the impact of public health emergencies on pregnant women and infants, with limited mechanisms for linking pregnant women with their infants nationally to monitor long-term effects. In 2019, the Centers for Disease Control and Prevention (CDC), in close collaboration with state, local, and territorial health departments, began a 5-year initiative to establish population-based mother-baby linked longitudinal surveillance, the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET). OBJECTIVES: The objective of this report is to describe an expanded surveillance approach that leverages and modernizes existing surveillance systems to address the impact of emerging health threats during pregnancy on pregnant women and their infants. METHODS: Mother-baby pairs are identified through prospective identification during pregnancy and/or identification of an infant with retrospective linking to maternal information. All data are obtained from existing data sources (e.g., electronic medical records, vital statistics, laboratory reports, and health department investigations and case reporting). RESULTS: Variables were selected for inclusion to address key surveillance questions proposed by CDC and health department subject matter experts. General variables include maternal demographics and health history, pregnancy and infant outcomes, maternal and infant laboratory results, and child health outcomes up to the second birthday. Exposure-specific modular variables are included for hepatitis C, syphilis, and Coronavirus Disease 2019 (COVID-19). The system is structured into four relational datasets (maternal, pregnancy outcomes and birth, infant/child follow-up, and laboratory testing). DISCUSSION: SET-NET provides a population-based mother-baby linked longitudinal surveillance approach and has already demonstrated rapid adaptation to COVID-19. This innovative approach leverages existing data sources and rapidly collects data and informs clinical guidance and practice. These data can help to reduce exposure risk and adverse outcomes among pregnant women and their infants, direct public health action, and strengthen public health systems.

Low Risk of Progression of Barrett's Esophagus to Neoplasia in Women.

BACKGROUND AND AIMS: Men are at a higher risk for Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC), but little is known about BE progression to dysplasia and EAC in women. We performed a retrospective, multicenter cohort study to assess risk of BE progression to dysplasia and EAC in women compared with men. We also investigated comorbidities, medication use, and endoscopic features that contribute to sex differences in risk of BE progression. METHODS: We collected data from large cohort of patients with BE seen at 6 centers in the United States and Europe, followed for a median 5.7 years. We obtained demographic information (age, sex, ethnicity), clinical history (tobacco use, body mass index, comorbidities), endoscopy results (procedure date, BE segment length), and histopathology findings. Neoplasia was graded as low-grade dysplasia, high-grade dysplasia (HGD), or EAC. Rates of disease progression between women and men were compared using χ2 analysis and the Student t test. Multivariable logistic regression was used to assess the association between sex and disease progression after adjusting for possible confounding variables. RESULTS: Of the total 4263 patients in the cohort, 2145 met the inclusion criteria, including 324 (15%) women. There was a total of 34 (1.6%) incident EACs, with an overall annual incidence of 0.3% (95% confidence interval: 0.2%-0.4%). We found significant differences between women and men in annual incidence rates of EAC (0.05% for women vs. 0.3% in men; P=0.04) and in the combined endpoint of HGD or EAC (0.1% for women vs. 1.1% for men; P<0.001). Female gender was an independent predictor for reduced progression to HGD or EAC when rates of progression were adjusted for body mass index, smoking history, race, use of aspirin, nonsteroidal anti-inflammatory drugs, proton-pump inhibitors, or statins, hypertriglyceridemia, BE length, and histology findings at baseline (hazard ratio: 0.11; 95% confidence interval: 0.03-0.45; P=0.002). CONCLUSIONS: In a multicenter study of men versus women with BE, we found a significantly lower risk of disease progression to cancer and HGD in women. The extremely low risk of EAC in women with BE (0.05%/y) indicates that surveillance endoscopy may not be necessary for this subgroup of patients with BE.

Crohn's disease in low and lower-middle income countries: A scoping review.

BACKGROUND: While Crohn's disease has been studied extensively in high-income countries, its epidemiology and care in low and lower-middle income countries (LLMICs) is not well established due to a lack of disease registries and diagnostic capacity. AIM: To describe the published burden, diagnostic/treatment capacity, service utilization, challenges/barriers to individuals with Crohn's in LLMICs and their providers. METHODS: We conducted a scoping review utilizing a full search strategy was developed and conducted in PubMed, Embase and World Health Organization Global Index Medicus. Two independent reviewers screened the titles and abstracts of all of the publications found in this search, reviewed selected publications, and extracted relevant data, which underwent descriptive review and was analyzed in Excel. RESULTS: The database search yielded 4486 publications, 216 of which were determined to be relevant to the research questions. Of all 79 LLMICs, only 21 (26.6%) have publications describing individuals with Crohn's. Overall, the highest number of studies came from India, followed by Tunisia, and Egypt. The mean number of Crohn's patients reported per study is 57.84 and the median is 22, with a wide range from one to 980. CONCLUSION: This scoping review has shown that, although there is a severe lack of population-based data about Crohn's in LLMICs, there is a signal of Crohn's in these settings around the world.

Burden of non-communicable diseases from infectious causes in 2017: a modelling study.

BACKGROUND: Non-communicable diseases (NCDs) cause a large burden of disease globally. Some infectious diseases cause an increased risk of developing specific NCDs. Although the NCD burden from some infectious causes has been quantified, in this study, we aimed to more comprehensively quantify the global burden of NCDs from infectious causes. METHODS: In this modelling study, we identified NCDs with established infectious risk factors and infectious diseases with long-term non-communicable sequelae, and did narrative reviews between April 11, 2018, and June 10, 2020, to obtain relative risks (RRs) or population attributable fractions (PAFs) from studies quantifying the contribution of infectious causes to NCDs. To determine infection-attributable burden for the year 2017, we applied estimates of PAFs to estimates of disease burden from the Global Burden of Disease Study (GBD) 2017 for pairs of infectious causes and NCDs, or used estimates of attributable burden directly from GBD 2017. Morbidity and mortality burden from these conditions was summarised with age-standardised rates of disability-adjusted life-years (DALYs), for geographical regions as defined by the GBD. Estimates of NCD burden attributable to infectious causes were compared with attributable burden for the groups of risk factors with the highest PAFs from GBD 2017. FINDINGS: Globally, we quantified 130 million DALYs from NCDs attributable to infection, comprising 8·4% of all NCD DALYs. The infection-NCD pairs with the largest burden were gastric cancer due to H pylori (14·6 million DALYs), cirrhosis and other chronic liver diseases due to hepatitis B virus (12·2 million) and hepatitis C virus (10·4 million), liver cancer due to hepatitis B virus (9·4 million), rheumatic heart disease due to streptococcal infection (9·4 million), and cervical cancer due to HPV (8·0 million). Age-standardised rates of infection-attributable NCD burden were highest in Oceania (3564 DALYs per 100 000 of the population) and central sub-Saharan Africa (2988 DALYs per 100 000) followed by the other sub-Saharan African regions, and lowest in Australia and New Zealand (803 DALYs per 100 000) followed by other high-income regions. In sub-Saharan Africa, the proportion of crude NCD burden attributable to infectious causes was 11·7%, which was higher than the proportion of burden attributable to each of several common risk factors of NCDs (tobacco, alcohol use, high systolic blood pressure, dietary risks, high fasting plasma glucose, air pollution, and high LDL cholesterol). In other broad regions, infectious causes ranked between fifth and eighth in terms of crude attributable proportions among the nine risks compared. The age-standardised attributable proportion for infectious risks remained highest in sub-Saharan Africa of the broad regions, but age-standardisation caused infectious risks to fall below dietary risks, high systolic blood pressure, and fasting plasma glucose in ranked attributable proportions within the region. INTERPRETATION: Infectious conditions cause substantial NCD burden with clear regional variation, and estimates of this burden are likely to increase as evidence that can be used for quantification expands. To comprehensively avert NCD burden, particularly in low-income and middle-income countries, the availability, coverage, and quality of cost-effective interventions for key infectious conditions need to be strengthened. Efforts to promote universal health coverage must address infectious risks leading to NCDs, particularly in populations with high rates of these infectious conditions, to reduce existing regional disparities in rates of NCD burden.

Availability of equipment and medications for non-communicable diseases and injuries at public first-referral level hospitals: a cross-sectional analysis of service provision assessments in eight low-income countries.

CONTEXT AND OBJECTIVES: Non-communicable diseases and injuries (NCDIs) comprise a large share of mortality and morbidity in low-income countries (LICs), many of which occur earlier in life and with greater severity than in higher income settings. Our objective was to assess availability of essential equipment and medications required for a broad range of acute and chronic NCDI conditions. DESIGN: Secondary analysis of existing cross-sectional survey data. SETTING: We used data from Service Provision Assessment surveys in Bangladesh, the Democratic Republic of the Congo, Ethiopia, Haiti, Malawi, Nepal, Senegal and Tanzania, focusing on public first-referral level hospitals in each country. OUTCOME MEASURES: We defined sets of equipment and medications required for diagnosis and management of four acute and nine chronic NCDI conditions and determined availability of these items at the health facilities. RESULTS: Overall, 797 hospitals were included. Medication and equipment availability was highest for acute epilepsy (country estimates ranging from 40% to 95%) and stage 1-2 hypertension (28%-83%). Availability was low for type 1 diabetes (1%-70%), type 2 diabetes (3%-57%), asthma (0%-7%) and acute presentations of diabetes (0%-26%) and asthma (0%-4%). Few hospitals had equipment or medications for heart failure (0%-32%), rheumatic heart disease (0%-23%), hypertensive emergencies (0%-64%) or acute minor surgical conditions (0%-5%). Data for chronic pain were limited to only two countries. Availability of essential medications and equipment was lower than previous facility-reported service availability. CONCLUSIONS: Our findings demonstrate low availability of essential equipment and medications for diverse NCDIs at first-referral level hospitals in eight LICs. There is a need for decentralisation and integration of NCDI services in existing care platforms and improved assessment and monitoring to fully achieve universal health coverage.
